Prepayment functions

  1. The meter can be integrated with relay and will disconnected from the power in some case, such as over load, over voltage, tampering, remote control and so on.

  2. The meter is recharged through CIU, the main prepayment functions are:

 2.1 Charging
 2.2 Remaining credit alarms (the alarm limit is configurable)
 2.3 Anti-electricity hoarding (the credit hoarding is configuration)
 2.4 Overdraft (credit is configuration)
 2.5 Friendly credit, In this mode, the relay will be off even is the credit is not enough.
 3.The meter can also be configured to post-payment mode for user’s convenience
